Referring to fig. 4 to 6, the bicycle lock 100 of the present embodiment includes a seat 110, a rotating member 120, a driven member 130 and a lock tongue 140. The follower 130 is movably disposed on the base 110 along a first direction D1. The rotating element 120 is, for example, a screw rod and is rotatably connected to the base 110 along an axial direction a parallel to the first direction D1, and the rotating element 120 has a thread 120a and is screwed to the follower 130 through the thread 120 a. The tongue 140 is movably disposed on the base 110 along a second direction D2 perpendicular to the first direction D1 and has an inclined surface 140a, and the inclined surface 140a is inclined to the first direction D1 and the second direction D2.

Specifically, the latch tongue 140 of the present embodiment includes a body portion 142 and a tongue portion 144 that are integrally connected, the body portion 142 is movably disposed on the seat 110 along the second direction D2, the inclined surface 140a is formed on the body portion 142, and the tongue portion 144 is used for engaging with the functional component 54 to perform the locking. On the other hand, the follower 130 includes a body portion 132 and a protrusion 134 integrally connected, the body portion 132 is screwed with the rotary member 120, and the protrusion 134 protrudes from the body portion 132 to correspond to the inclined surface 140a of the latch tongue 140.

FIG. 9 is a perspective view of the bicycle lock of FIG. 7 from another perspective. The rotating member 120 is adapted to rotate in the axial direction a to drive the driven member 130 to move from the position shown in fig. 4 and 5 to the position shown in fig. 7 and 8 along the first direction D1, and the moving driven member 130 is adapted to drive the locking tongue 140a to move from the unlocking position shown in fig. 4 and 6 to the locking position shown in fig. 7 and 9 along the second direction by the protrusion 134 pushing the inclined surface 140a of the locking tongue 140, so that the tongue 144 of the locking tongue 140a locks the functional component 54 mounted on the bicycle 50.

Since the bicycle lock 100 of the present embodiment drives the locking tongue 140 to lock by rotating the rotating member 120 as described above, a user can unlock or lock the bicycle lock 100 by only rotating the rotating member 120 without carrying a corresponding key, thereby improving the convenience of the bicycle lock 100 in use. In addition, since the rotating member 120 rotates in a stepless manner to perform the locking, rather than in a two-stage manner as a conventional key, the user can rotate the rotating member 120 to make the latch 140 firmly abut against the locked functional element 54, so as to prevent the functional element 54 from shaking excessively during the riding process.

FIG. 10 is an enlarged partial view of the bicycle of FIG. 1. FIG. 11 illustrates the operation of the bicycle lock of FIG. 10 with a tool. In the present embodiment, one end of the rotating element 120 has a non-circular hole 120b as shown in fig. 3, and the non-circular hole 120b is, for example, a torx hole suitable for a ring spanner. In other embodiments, the non-circular hole 120b may be a hexagonal hole suitable for a hexagonal wrench or may be a non-circular hole with other shapes, which is not limited in the present invention. The other end of the rotating member 120 is screwed to the follower 130. The frame 52 has an opening 52a to expose a non-circular aperture 120b. The user can insert a tool 60 (such as a hex wrench) into the non-circular hole 120b as shown in fig. 11 and rotate the tool 60 for more than 360 degrees to rotate the rotating member 120, so as to move the latch tongue 140 from the unlocking position to the locking position. The allen wrench is a tool that many users carry when riding the bicycle to adjust or repair the body of the bicycle, and the bicycle lock 100 of the present embodiment can be locked and unlocked by using the existing tool.

FIG. 12 is a partial component perspective view of the bicycle lock of FIG. 3. Referring to fig. 12, the bicycle lock 100 of the present embodiment includes at least one first elastic member 150 (two are shown), wherein the first elastic member 150 is, for example, a compression spring and is connected between the seat 110 and the latch 140. When a user wants to unlock, the rotating member 120 may be rotated to move the follower 130 from the position shown in fig. 7 and 8 to the position shown in fig. 4 and 5 in the reverse direction of the first direction D1, and then the latch 140 is released by the follower 130 and is reset from the locked position shown in fig. 7 and 9 to the unlocked position shown in fig. 4 and 6 in the reverse direction of the second direction D2 by the elastic force of the first elastic member 150.

In the embodiment, the latch tongue 140 includes an extension portion 146 connected to the body portion 142, and two ends of the extension portion 146 protrude from the body portion 142. Two first elastic members 150 are respectively connected to two ends of the extending portion 146. In other embodiments, the latch 140 may have other suitable shapes to be suitable for connecting the first elastic member 150, which is not limited in the present invention.

The bicycle lock 100 of this embodiment further includes a second resilient member 160 as shown in fig. 5. The second elastic element 160 is, for example, a compression spring, and is sleeved on the rotating element 120 and connected between the base 110 and the follower 130. The follower 130 is suitable for being positioned on the base 110 by the elastic force of the second elastic element 160, and the rotating element 120 needs to resist the elastic force of the second elastic element 160 to drive the follower 130 to move when rotating. By the configuration of the second elastic member 160, the loosening of the follower 130 due to insufficient engagement between the external thread 120a of the rotating member 120 and the corresponding internal thread of the follower 130 can be avoided.

FIG. 13 is a partial cross-sectional view of the components of the bicycle lock of FIG. 3. In the present embodiment, the rotating element 120 includes a first shaft portion 122 and a second shaft portion 124 which are coaxial as shown in fig. 13, the first shaft portion 122 is connected to the base 110 and the driven element 130, and the second shaft portion 124 is rotatably connected to the first shaft portion 122 with a predetermined torque value. The second shaft portion 124 is adapted to rotate the first shaft portion 124 under an external force smaller than a predetermined torque value. Therefore, when the rotating element 120 rotates to drive the driven element 130 to move to the limit position shown in fig. 3 or fig. 8, if the user continuously rotates the rotating element 120 and the torque force is greater than the predetermined torque force value, the second shaft portion 124 will start to rotate relative to the first shaft portion 122, so as to prevent the rotating element 120 and the driven element 130 from being damaged by the excessive torque force.

In summary, the lock for bicycles of the present invention drives the lock tongue to lock by rotating the rotating member, and the user can unlock or lock the lock for bicycles by rotating the rotating member with a tool (such as a hexagon wrench) without carrying a corresponding key, thereby improving the convenience of the lock for bicycles. In addition, since the rotating member rotates in a stepless manner to perform the locking, rather than in a two-stage manner as in the case of a conventional key, a user can rotate the rotating member to ensure that the latch bolt is firmly abutted against the locked functional element, thereby preventing the functional element from shaking excessively during riding.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
